SLITTING AND WINDING- MECHANISM.

To all whom it may concern:

Be it known that I, PoNTUs HELLEERG, residing at 1G Furnival Mansions, Vells street, Oxford street, London, l/V., England, have invented certain new and useful Improvements in Slittingand linding Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the production of a number of strips from a single web of paper for the purpose of spinning into threads or the like and has for its object to provide means whereby a comparatively large number of strips may be produced with suiiicient space in which each strip may be manipulated when wound on to bobbins or when passed direct to adjacent spinning machines, thus enabling a large number of strips to be dealt with simultaneously, which greatly cheapens the cost of production.

Apparatus has already been employed for cutting a web of paper into strips which pass over guide rollers and are wound on a series of bobbins disposed on two shafts; said shafts and guide rollers respectively being disposed one above the other. Further it has been proposed in the manufacture of yarns or threads from paper pulp, to pass the separate strips in groups to a plurality of bobbins arranged in several lines, each corresponding strip ofthe said groups being passed to bobbins in the same line, but without employing a separate guide roller for each line of bobbins.

The invention consists in cutting a web of paper into strips and then passing the so formed strips in groups over a plurality of rollers disposed in a substantially horizontal plane each corresponding strip of the said groups being passed round one and the same of the said rollers to either the bobbins or spinning spindles. I may also provide damping rollers for damping the strips before reaching the spinning spindles. I prefer to employ seven rollers as a convenient number, but in any case there are to be more than two.

In order that this invention may be more fully understood it will now be described with reference to the accompanying drawings, in which Figure 1 is a diagrammatic plan of a machine constructed according to this invention, illustrating the arrangement of the strips, and Fig. 2 is a diagrammatic side elevation thereof illustrating alternative manners of dealing with the strips after cutting.

In' carrying this invention into practical effect and as shown, the roll of finished paper a is mounted upon bearings al in the usual manner, the sheet passing between cutting rollers b, also as is well understood these cutting rollers cutting the sheets into strips which pass between conveying rollers c thence to a second pair of conveying rollers d mounted upon a bench c which also carries a series of (as shown) seven rollers 1 to 7. The paper strips pass one over each roller l to 7 so that they become divided into what may be termed series or groups of seven strips each, two complete series or groups being shown in Fig. l, marked 11 to 71 and 12 to 72 respectively, so that strips l1 and 12 pass over roller 1, 21 and 22 over roller 2 and so on. This arrangement affords a considerable space between the strips passing over each roller so that upon axles g (Fig. 2) mounted beneath the said rollers, upon the frame e, winding spools or bobbins h may be mounted, upon which all the strips may be wound simultaneously, the bobbins li being revolved by convenient means. As an alternative to winding the strips upon the bobbins 7i, they may pass direct to the spinning spindles z' over rollers l which may be damping rollers of suitable form, and it is preferred that each spinning machine carry two spindles as indicated in Fig. 2, so that each machine will deal with two strips, for instance, 11 and 21, 31 and 41, 51 and 61, 12 and 22, 32 and 42, 52 and 62.

I claim- The combination, with a support for a `roll of paper, and cutting mechanism for severing the paper longitudinally into a series of strips as it leaves the roll; of a series of pairs of guide rollers arranged one behind another in the same plane, the said strips being divided into similar groups and each group having strips corresponding in number to the number of pairs of guide rollers, one corresponding strip of each group being passed between all the pairs of I of each group of strips which pass to it from 10 guide rollers, two corresponding strips of r the pair of guide rollers pertaining to it.

each group being passed between all the In testimony whereof I aliX my signature, pairs of guide rollers except the last pair l in presence of two witnesses.

of the series and so forth and all the strips being passed between the irst pair of guide PONTUS HELLBERG' rollers, and a separate winding device ar- Witnesses: ranged under each pair of guide rollers and C. ERIC CLOUGH, operating to wind the corresponding strips A. W. VINSALL.
